Dear George, it's very simple. my art students can take a picture to make a portrait for study, but they don't publish their studies to monetize!
But to learn how to draw.

On Steemit the rules are there and must be respected.

For several reasons:
1-because users vote for you with money.
2- out of respect for other artists who publish original works
3- an experienced user like this we are talking about these rules knows them very well!

4- out of respect for other artists who have their photographs under copyrights.

Ciao caro amico.
